SPECIFICATION forming part of Letters Patent No. 784,333, dated March'7, 1905.

Application sled July 2, 1904. semi 110.215.170.

arrange the centrifugally-actuated part or parts that the movementthereof will be attended by the least possible friction, thus increasingthe sensibility of the governor, permitting it to respond effectually toany slight variations in the speed of the driving apparatus. I attainthis end by certain novel features of structure and organization, whichwill be fully set forth hereinafter and pointed out in the claims.

Reference is had to the accompanying drawings, forming part of thisspecification and illustrating as an example one embodiment of myinvention, in which drawings like letters of reference indicate likeparts in the several views, and in which- Figure 1 is a longitudinalsection of the governor essentially on the line 1 1 of Fig. 2.

Fig. 1 is an enlarged detail sectional view on the line 1" 1 of Fig. 4,showing the frictionless connection between the centrifugally-actuatedweights. Fig. 2 is a cross-section on the line 2 2 of Fig. 1. Fig. 3 isa fragmentary cross-section on the line 3 3 of Fig. 1, and Fig. 4 is asectional plan on the line L 4 of Fig. 1^.

According to the example of the invention here given the moving partsare inclosed in a case formed of two sections 10 andll, suitablyfastened together and revolubly mounted through the medium of tubularjournals 1()2L and 11", carried in supports 12. 14 may be taken toindicate a band-pulley, through the medium of which the case may berevolubly driven. IVithin the case are arranged two weights 15, providedwith knife-edges 16,1ockably mounted on corresponding bearing-plates 17,located within the case, said weights being arranged to swing aroundaxes coincident with 'the edges of the knives 16 through an are ofmovement limited by abutments 10b and 11b, formed on the interior wallsof the case. The weights 15 are held yieldingly in the intermediateposition shown in Fig. 1 by a spring 18. This spring is helical orspiral and has its end portions engaged in corresponding grooves formedin blocks 19, said blocks acting essentially as nuts, and by adjustingthespring on the blocks the tension of the spring may be regulated atwill to regulate the governor, as will be understood. Said nuts orblocks 19 have wear-plates 20 secured thereto and engaged by knife-edges21, attached to rings 22. Said rings are engaged by bolts 23 to extendoutward through the nuts 19 and have their outer ends engaged withcross-bars 24, which are connected with the respective weights 15through the medium of knifeedges 25, engaged with wear-plates 26,secured to the weights. It will be observed that by these means thespring 18 is connected with the weights, so as to exert on them thenecessary restraininginfluence and at the same time to eliminate for allpractical purposes any friction incident to the swinging movement of theweights relatively to the spring. One of the weights has a fork 27attached thereto, and this fork is pivotedto a horizontally-disposedfork 28, in turn connected with a sliding rod 29, extending through thehollow journal 10" and serving to transmit to the part being actuatedthe movement of the governor. The weights 15 are connected to move inunison by means of arc-shaped members 30, connected, respectively, tothe fork 27 and to bracket31, attached to the weight not having thefork. The arc-shaped members 30 have their arc-shaped faces opposing'each other, and these members are connected by flexible metallic bands32, each band having one end attached to one of the members 30 andclosing over with its other end in connection with the other arc-shapedmember 30. `With this device the parts 15 are positively connected, yetmovement is allowed and transmitted without friction of any sort.

As the governor is rotated and the Weights move outward undercentrifugal force they rock around the center of the edges of the blades16, expanding the spring 18.k The swinging movement kof the weighthaving the fork Q7 is directly transmitted through the fork 28 to therod 29, and the swinging movement of the other weight is transmittedthrough the straps or bands 32. It will be observed that the weights arenot hung on journals or pivots and are consequently free from thefriction incident to these members. They are merely suspended betweenthe knifeedges, and their movement produces nothing more than a rollingmovement of the knifeedges, which will be without friction, as will beunderstood. l,

Various changes in the form, proportions, and minor details of myinvention maybe resorted to at will'without departing from the spiritand scope thereof. Hence I consider myself entitled to all suchvariations as may lie within the terms of my claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A governor having two weights, and means formovably mounting the same, said means comprising knife-edges and membersengaged therewith, and aconnection between the weights.

2. A governor comprising two Weights, means for movably mounting thesame, comprising knife-edges and coacting members engaged therewith,said mounting means being located at the outer portions of the weightscausing them t0 move in unison, and a connection between the innerportions of the weights causing them to move in unison.

3. A governor comprising two weights, means for movably mounting thesame, comprising knife-edges and coacting members engaged therewith,said mounting means being located at the outer portion of the weights, aconnection between the inner portions of the weights causing them tomove in unison. and means for yieldingly holding the weights in inactiveposition.` 4. A governor comprising two weights, means for movablymounting the same, comprising knife-edges and coacting members engagedtherewith, said mounting means being located at the outer portions ofthe weights, a connection between the inner portions of the weights, aspring, and means for connecting the spring with the weights, said meanscomprising knife-edges and coacting members engaged therewith.

5. A governor comprising two centrifugally-actuated weights movable fromand toward each other, a spring, and means connecting the ends of thespring respectively with the weights,said means comprising lmifeedgesand coacting members engaged with the knife-edges.

6. A governor having a movable weight, a

spiral or helical spring, a correspondinglygrooved block loosely engagedwith the spring, and means for connecting the block with the weight.

7. A governor having a movable weight, a spiral or helical spring, acorrespondinglygrooved block loosely-'engaged with the spring, and meansfor connecting the block with the weight, said means comprising aknife-edge Vand a member engaged therewith.

8. A governor having a movable weight, a spiral or helical spring, acorrespondinglygrooved block loosely engaged with the spring. means forconnecting the block with the weight, said means comprising a knife-edgeengaged with the member, a ring mounting the knife-edge, a bolt engagedwith the ring, a cross-bar engaged with the bolt, and knifeed ges at theends of the cross-bar and engaged with the weight.

9. A governor having a movably-mounted weight,v a spring, a member inconnection with the spring, a knife-edge engaged with the member, a ringcarrying the knife-edge. a bolt connected to the ring, a cross-barengaged with the bolt, and a knife-edge on the cross-bar and engagedwith the weight.

10. A governor comprising two movable weights, means for transmittingthe movement of the governor, said means being in direct connection withone weight, and a connection between the weights.

11. A governor comprising two weights. a member directly connected withone weight to transmit the movement thereof, and a ilexible connectionbetween the two weights.

12. A governor comprising two weights, and flexible bands having theirends respectively connected with the weights, the bands crossing eachother to transmit swinging movement from one weight to the other ineither direction.

13. A governor comprising two swinging weights having arc-shaped membersconnected therewith, and crossing iexible bands having their endsrespectively connected with the varc-shaped members to transmit movementHERMANN KRONER.
